|
This module exploits a vulnerability in SysAid Help Desk that allows an unauthenticated
|
|
user to create an administrator account. Note that this exploit will only work once. Any
|
|
subsequent attempts will fail. On the other hand, the credentials must be verified
|
|
manually. This module has been tested on SysAid 14.4 in Windows and Linux.
